I. Overview and Technical Index
1. Overview
HZCS-3 transformer oil acid tester is a fully automatic measuring instrument
which adopts the extraction method to accurately detect the insulating oil
acid value. This instrument can improve the working efficiency and test
accuracy, and at the same time ensure the safety of the body by reducing
the operator's contact with the samples and reagents.
The instrument will automatically search the samples, inject the
extraction, make a blank titration, do an experiment, clean off, display
printing results and other operations as long as the operator put the
sample cups in the sample cup holes and inject the extraction in the cup.
Once started, 1 to 3 samples can be measured, which is convenient and
high efficiency.
Because of the preparation of the standard acid for instrument calibration
and calibration procedure, the clients can calibrate the instrument and the
neutralizing liquid at any time so that the instrument can overcome the
defect of changes in concentration of neutralizing liquid during use. At the
same time, during the test the instrument will automatically deduct the
background value of the extract so that the instrument can ignore the
influence from the change of background value on the extraction. All these
design make the result more accurate and reliable.
